Updating two tables

Only the partitions (or subpartitions) listed are checked for matches, and a row that is not in any of these partitions or subpartitions is not updated, whether it satisfies the clause, are flagged as unsafe for statement-based replication.

(This is because the order in which the rows are updated determines which rows are ignored.) Such statements produce a warning in the error log when using statement-based mode and are written to the binary log using the row-based format when using mode.

I am displaying the information in a datatable but there is just one field editable as a drop down list.

When I change it I got the correct information as you can appreciate it on the image attached, but when I received in the controller same Id key is taken for both tables to be updated.

When used in the subquery of a DML statement, you can specify this clause in a subquery in the can be a subquery, a column, a function, or a collection constructor.

Regardless of its form, it must return a collection value—that is, a value whose type is nested table or varray.

The returning clause retrieves the rows affected by a DML statement.

If you access a column from the table to be updated in an expression, assignments are generally evaluated from left to right.

I would like to know how can I send to the controller two different values as a key for each table to be updated if possible.

Every now and then you will get someone asking how to update two tables with one statement in SQL Server. the person then walks away muttering something about how My SQL allows it.

Cross table update (also known as correlated update, or multiple table update) in Oracle uses non-standard SQL syntax format (non ANSI standard) to update rows in another table. Update data in table A based on two or more common columns in table B.

The differences in syntax are quite dramatic compared to other database systems like MS SQL Server or My SQL. Updates based on two or more common columns are normally used for tables where multiple columns work together as a primary key (known as composite primary key).

For multiple-table updates, there is no guarantee that assignments are carried out in any particular order.
